That's about a decade and a half too late. We need to be reducing our carbon footprint right now, and we have that ability: wind and solar. Low initial impact, fast to net carbon negative.

Nukes take decades to dig themselves out of their carbon positive holes, if they ever do so at all (the nuclear industry does not account for most of the CO2 generated from supply and operations.)
